hierarchical multi-cursor editor

To initiate discussion of this initial working release,and seeing local discussion is kept to this forum(although I think the editor may warrant its own messageboard),here are some errata corresponding to this release:

s.cc is no longer needed, it was used to track a bug when using malloc.the opendir() call seems to be generating errors sometimes,perhaps malloc errors but not debugged yet: this call is superfluousto the design of the editor as of now and may be removed fromterm::expand(). start the program on different machines like this:route add -net 224.0.0.0 netmask 224.0.0.0 dev eth0./main 1234(and on other machine)route add -net 224.0.0.0 netmask 224.0.0.0 dev eth0./main 4321(all participants currently must start with the editorin the initial empty state.)

further documentation or discussion should be forthcomingwith your interest.
